All of that is wrapped in a lengthy memo that lays out what Democrats see as examples of Mourdock's extremism. Democrats think Mourdock's victory over Sen. Dick Lugar in Tuesday's primary gives their candidate, Rep. Joe Donnelly, a better chance.

The National Republican Senatorial Committee fired off its own memo making the case for Mourdock Tuesday night, and followed up Wednesday by saying Donnelly should apologize for voting with President Barack Obama.

Hoosiers want a senator who will stand up to the big spenders in both political parties in order to cut spending, balance the budget, and get our economy on track. That's what Tuesday's election was about. Joe Donnelly went along with Barack Obama by voting for Obamacare, the failed stimulus, and bailouts. Richard Mourdock is a tested two-term statewide official in one of the few states in the country with a genuinely balanced budget. A few web ads aren't going to change this.
